Carbon steel pipes are tubular steel products widely used for fluid transportation, structural applications, and mechanical manufacturing. Available in both seamless and welded constructions, and in thick wall and thin wall specifications, they offer excellent strength, weldability, and cost-effectiveness for a broad range of industrial applications.
Our carbon steel pipes are produced to international standards including ASTM A106, ASTM A53, API 5L, GB/T 8163, and GB/T 3091, and are available in grades such as A106 Gr.B, A53 Gr.B, Q235B, Q345B, 20#, and 45#.
| Type | Definition | Typical Process | Typical Applications |
|---|---|---|---|
| Thick Wall Pipe | Wall thickness / OD ≥ 0.02 (D/S ≤ 20) | Hot rolled, cold drawn | High pressure, boiler, hydraulic systems, structural columns |
| Thin Wall Pipe | Wall thickness / OD < 0.02 (D/S > 20) | Cold drawn, ERW welded | General piping, fluid transportation, machinery frames, furniture |
Note: Thick wall pipes are designed for pressure-bearing and load-bearing applications, while thin wall pipes are typically used for general conveyance and structural purposes.
